SYSCONFIG: MSP432E401Y + SysConfig = No Quad SPI

Part Number: SYSCONFIG
Other Parts Discussed in Thread: MSP432E401Y

Using SysConfig 1.24 (standalone)..

if I create a bare-metal project, then I can select SSI and allocate a QUAD-mode SPI bus.
however if I create an SDK project, it says SPI and won't let me allocate the QUAD ports.

Same problem allocating Timer pins: I can do this in bare-metal, but not in SDK

Any ideas?

Hello Matthew,

I can see the issue where the SSI selection is not available when using the MSP432E401Y SDK, however, can you elaborate more on the QUAD-mode SPI? The MSP432E401Y does not support Quad-SPI, so this would not be available in the SDK.

Thanks,

Hi Eric,

If you check the spi_serialflash (MX66L51235F) example in the MSP432E401Y SDK (NO RTOS), you can see that the device does support QSSI. The issue is that QSSI wasn’t ported to TI‑RTOS, so the option doesn’t appear in the TI‑RTOS SDK.

Thanks,

Niwantha

Hi Niwantha/Mathew,

SysConfig generates the ti_msp_dl_config.h and ti_msp_dl_config.c files which the project uses to build. As a workaround, you should be able to generate your own source and header files to configure the QSSI.

Thanks,
